DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle for transporting a long metal plate or the like on a roof surface.

[0002]

2. Description of the Related Art In recent years, on the roof surface of a large building such as a factory facility or a gymnasium, a metal folded sheet roof in which a metal sheet is formed by folding a chevron on a metal sheet is inexpensive. It is spreading because the construction cost can be reduced. When laying a metal folded plate on the roof surface, a large number of workers manually carry the metal folded plate to the roof surface and accumulate the metal folded plate, or stack a number of the accumulated metal folded plates on the roof surface. While transporting to the predetermined roofing position, the metal folded plates are placed one by one in the flow direction of the roof surface, and the mutual end faces of the adjacent metal folded plates are overlapped and jointed to form a chevron and a valley. It is laid sequentially.

[0003]

However, the metal folded plate has a shape of about 60 cm in width and about 30 to 40 m in length, depending on the area of the roof surface to be laid. Workers manually transport the folded plates to the roof surface and accumulate them, or transport them to a predetermined position along the roof surface and lay them, which requires a lot of work with many workers and is highly efficient. However, there was a problem that the work could not be performed and the danger during the work was high.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide an endless rail having a plurality of rail-shaped plates fixed to an outer surface of an endless belt on a rectangular machine frame which is long in front and rear. While arranging a plurality of transport vehicles equipped with parts on the roof surface, place a long plate-shaped object to be transported such as a folded metal plate on each transport vehicle and move it in a direction intersecting the flow direction of the roof surface. During transportation, the infinite rails of the transport vehicle do not bite into the end face of the chevron and do not stop, so that the transport vehicle can be transported efficiently by a small number of people while moving smoothly, and the risk of work is small. It is an object of the present invention to provide a rooftop carrier characterized by the following.

[0005]

Means for Solving the Problems In order to achieve the above object, an invention according to claim 1 is a vehicle for roof use used on a metal folded plate roof in which chevron portions and valley portions are formed alternately. A machine frame 12 assembled in a long rectangular shape long before and after,
An infinite rail portion 14 provided near the machine frame to support the machine frame 12 and provided in a circumferential shape in the longitudinal direction thereof.
The infinite rail portion 14 is provided with wheels 28, 28 for infinite rails mounted on the front and rear end sides of the machine frame 12, and tuned in a circular shape around the infinite rail vehicles 28, 28. An infinite rail band 30, wherein the infinite rail band 30 is an endless belt 38 wrapped around the infinite rail wheels 28, 28.
And a plurality of rail plates 40 fixed in series adjacently to the outer peripheral surface of the endless band 38, and further, the rail plates 40 adjacent to each other of the rail plates 40 are not connected to each other, and The rail plate 40 is joined and fixed only to the outer surface of the endless band 38, and the abutting end faces of the mutually adjacent rail plates 40 are so arranged that the abutting positions of the adjacent rail plates 40 do not shift vertically. Engaging part 4 which can be fitted and disengaged from each other
4 is provided.

Further, in the invention according to claim 2, the machine frame 12 has a receiving portion 54 disposed on the upper surface side thereof, and the receiving portion 54 stands upright and falls down with respect to the machine frame 12. The standing and falling mechanism 56 that is freely supported, and the standing and falling mechanism 5
6 may be provided with a roller 58 supported by the shaft.

[0007]

The transport vehicle on a roof according to the present invention is used for transporting a long conveyed object such as a folded metal plate on the roof surface, at a position near the eaves in the flow direction of the roof surface, at an intermediate position, or near a ridge. A plurality of rooftop trucks will be installed at the location, etc. in parallel with the eaves and the ridge.
Then, a plurality of long plate-shaped objects to be conveyed, such as folded metal plates, are placed on the upper surface of the machine frame of each rooftop carrier, and are located at the end side of each rooftop carrier. An operator transports each of the on-roof transport vehicles to a predetermined location while pushing them in a direction intersecting the flow direction of the roof surface of the folded metal plate without power. After the transportation, each roof-top transportation vehicle is pushed back to the original position in the reverse direction, and the transported object is mounted again and transported. In each transport vehicle, the rails fixed in series to the outer surface of the endless belt bite the end faces of the chevron of the metal folded plate while the infinite rails rotate while sliding on the roof surface of the folded metal plate while moving. The endless rail section is capable of stabilizing the roof of the folded metal plate with the chevron section and valley section without indenting or shifting the mutual abutment surface of the rail plate at the end face position of the chevron section. It can move while rotating. Further, the long plate-shaped conveyed object can be efficiently transported by a small number of workers, so that the burden on the workers is reduced, and the safety at the time of work is improved. In addition, a long transported object such as a folded metal plate is placed on each rooftop carrier installed in parallel with the eaves or the ridge at the eaves near the eaves or in the middle position in the flow direction of the roof surface, or near the ridge. When loading, place the rollers above the machine frame by erecting the erecting / falling mechanism provided on the machine frame, and place a long transported object on the rollers of the carrier on the eaves side, and place another roller on the roof. It is pushed to the rollers, and finally the standing and falling mechanism is lowered, so that a long transported object can be easily placed on each transport vehicle.
